Be it known that'L'HnnBEn'rH; 0115mm,

a citizen of the United States, residing at San Leandro, in the county of Alameda and State of California, have inventedicertain new and useful Improvements Ovens; and I do hereby declare'the 'followingtobe a full, clear, and exactdescription i of the invention, such as will' enable others skilled in the art to which it appertainsf to .make and use the same. 1 1

This 'invention relates to'ovens and the primary obj ect of the invention is to provide an improved portable oven tor-use on top of stoves, of a compact nature, which will use only one burner or hole, andwill effectively confine and distribute -the heat therefrom, so that the articles the'oven will be readily cooked, with a minimum I e,

therelmand themeans tor holdlng the same] amount of fuel-and time.

Another object of the invention: is to: l pr0 vide an improved cooker 1 or oven,-which can be 7 effectively used for J baking bread, such as biscuits mu imdlthe like Custards" beans or for frying doughn and P PP ofrone oi the falseb'ottom I corn and in which thexp'arts' thereof can: be readily taken apart and used as skillets, in theordinary manner.

A =further ob'ect of the iIlVGIltlOll'flS to provide an improved oven including a pair of pivotally connected Skillets whichicanbe readily reversed, so that the same can be readily heated to the desired degree and which are adapted toreceive the articles to.

be cooked, and having. false. bottoms or plates .therein, which are so formed .asrto efl'ectively distribute'theiheat through the oven to evenly cook all portions of thearticles placeditherein." 1 p Another object of the inventiomis to provide an improved means fordtachably holdingthe false bottoms in position, whereby the same are prevented from accidental I displacement during the cooking operation.

A still turtherobjectof the'invention is to provide an'oven of-the above 'cha'racter having plurality of rigidly. connected rings, which are adapted" to be, placed in the oven and'which are :connected with the oven in such a manner that .the same can be readily reversed, so that the articles inthe rings can be readily cooked from the top and bottom. I

A; still further objectoi? the invention is to providean. improved cooker of the above @moved' therefrom, and

use, onethat is simple andeasy to manufacsp c i pf i j h -i ,1 Patented Au 10, 1920. .Application'filed June 2'5, 191 s.-.s fi i 11042413831 ture, and onethat can beplaced upon the y I market I at; a, reasonable cost.

ZWiththese and other objects in yiewthe nvention conslsts in the novel construction,

arrangement and formation 'ofparts,ias;will

be hereinafter: more specifically described, claimed and illustratedin the accompany ing drawing forminga part thereof, in

wherein similarf reference characters 'desigunate, corresponding; parts throughout the .-SGVGI'311 ,VlGWS, the numeral ,1, enerally indicatesflthe improved portab e oven, which includes angannular vbase 2, an upper skillet Band at lower skillet 4. 'jTheba'se 2includesja cylindrical body 5, -Fthe' inner lower surface ot which is inclined inwardly *asat j6, solthat the heat arising spherical socket 8-in-which is adapted to be positioned the; ballmem'ber 9 formed on-they arm 10ca'rried bythe free'edge of the lower vskillet 4; The ball member9 is provided with a diametrically extending aperture, which 1 communicates with a diagonally extending slot 12, which slidably receives thezpivot vpin311, which extends from the circular member 9*. carried by the free end of the" arm 9 formed on the upper skillet 3. The

terminals ofthepivotipin, 11 carried by the circular member 9 are flattened as at 13 and it vwill be seen thatwhen the upper skilletv tio'n to one "another.

-'apertures through the grooves 12 and the skillets readily detached, and thus allow the same to be used as separate cooking utensils in the ordinary manner.

The upper skillet'3 and the lower skillet each include the cylindrical side wallor body 14 and an end wall 15. When the skillets are in their closed position, as

clearly-shown in Fig. 21a complete closed housing is formed. Handles 16 and 17 are formedon the inner meeting edges of the upper and lower skillets 3 and l and'exten'd outwarclly therefrom and are diametrically opposite the pivot point of the skillets and form means whereby the oven 'can be readily handled and the-skillets operated in rela- The inner surfaces thereof are flattened, as at 18" for a purpose which will hereinafter more fully apl s V False-bottoms or heating plates 18 an'd 19 are arranged tobe placed-in 'the lower and upper skillets and each-includes a circular plate 20 having an outer annular row of perforations 21 and an inner concentric anro o'f perforations 22, which provides means whereby the heat may be readily circulated and distributed through the oven. The outer surfaces of the false bottoms 18 and 19 ar'e provided with :a plurality of spaced legs 23 on their outer surf-aces which are arranged toerrgagethe iirner surfaces *of the "walls of the upper and lower skillets, so as to 'space th'e plates therefrom. lheplates are held agaiaist accidental movement by means 'of spririgs 24 and 25, which "are secured to the false bottoms 18 {and 19 and arranged to engage the inner surfaces o'if'the sidewalls o f' the'sk-illets so as to fric- -'tiona;l ly =engagefthe same and hold the bot "tom's in position. The-springs '24 and 25 are 'ofsiibstantially annular formation :and are of the expansion type and have one end bent inwaird ly as at '26 into engagement with-the outer surfaces of the false bottoms and securedthereto *b'ysuitztble rivets 27.

The articles to be cooked are placed into the sk-i l lets between the bottoms 18 and :1 9 and it will be seen from the-formation of the same the heat will be evenly dist'rihuted throug h' the article's whereby the same will be eyenly 'and readily cooked.

, When it "is desired to eoek *muffins'or biscuits or the like a pluralit of annu-lar rings '28 which are preferably made of aluminum, -.orthe *like are inserted between the false bottoms and the'dough is placed therein and the oven is used iiithe ordinary manner. The rings 28 -are r'igidly 'connected' together and include-an outer annular row of rings Wand a central ring and the outer rings are .xhe'ld together at their upper and lower e'dges by apai r of spaced bands 29, which are held in spaced relation at diametrically spaced points-by means of braces 30. The braces 30 carry outwardly extending shafts 3'1 whichareadapted to seat in substantially semi-circular grooves 32 formed in the meeting edges of the upper and lower skillets 2 and One of the shafts 81 adjacent to the handles I6and 17 is extended to provide a handle 32, which is positioned intermediate the handles 16 and 17 and forms means whereby the rings can be readily inserted into'the skillets or the position thereof reversed, whereby biscuits 'or the like can be cooked in the top or bottom. c

When it is desired to reverse the lposition of the rings 28 in the skillets, the upper skillet 3 is raised as clearly shown in Fig. 1 and the handle '32 is grasped and raised upwardly until the rings are entirely out of engagement with the lower skillet, at which time the same are rotated at the outer shaft 31. The rings are then lowered in the lower skillet and the upper skillet is then closed.

WV'hen it is desired to reverse the position of the skillets, the handles 16 and 17 are grasped in one ha nd,vafter which the skillets are swung upwardly upon the ball and socket joint until the lower'skillet :is "raised clear of the base 2. While holding the skillets in that position, they are turned upon the ball and socket join-t until they are reversed, after which they are lowered into normal ;posit ion with respect to the base 2.

From the foregoing description it can be seen that an improved oven is provided, which is adapted to be positioned on etop of thestove, which is of-exceedinglyfsimpleand durable construction, in which -the articles being cooked can be cooked at an even temperature and thoroughly cooked a reliable and efficient manner. I

In :practice, have foundthat the form of my invention, illustrated in the accompanying drawings andreferred to the above description, as the preferred embodiments, is themost effioient and practical; yet realizing the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes 'in details of construction, proportion and arrangement of parts may be. resorted to, when required, without sacrificing any ;o':f the advalntages of my invention as set forth.
